Abstract

The invention relates to a method and a device for simultaneously representing at least a first and a second sequence of pictures (M, S) in an overall picture. The inventive method is characterised in that picture data belonging to a picture of the first sequence of pictures (M) is stored in the form of a first picture data signal in a first picture memory (SPM). Picture data belonging to a picture of the second sequence of pictures (S) is stored in the form of a second picture data signal in a second picture memory (SPS). The picture data of the first and second picture data memory is read out according to a periodic screen signal (RS), whereby phase shift (SHIFTM, SHIFTS, tx) of the screen signal (RS) can be adjusted according to the first and/or second picture data signal.
